Bluetooth Headset Recommendations??

I would have to say the jawbone. I have had 2 of them and loved them both. Good battery life, excellent sound quality. It is also comfortable to wear for long periods of time. One suggestion, use the loop that comes with it, it will make it more comfortable to wear and i use the gel piece with the small loop on the side, it seems to hold better in my ear.
The only drawback I have found is the other buttons. There are supposed to be some, I can't find them. lol
All in all, a bit more expensive than others, but well worth the money.
